Question
 In each of the questions, a sentence is divided into
five parts A, B, C, D and E in which two of the parts have some grammatical or contextual errors in them. You have to identify which pair among the given alternatives represents the parts that contain those errors. If none of the parts has any error, then mark option 5, i.e., ‘No error’ as your answer. While COVID-19 makes no difference (A)/  between rich and poor, countries  and province, (B)/ a lot can depend in the treatment (C)/ where the person is when it comes (D)/  to quality and cost of treatment (E) .Solution
B- In this part of the sentence, the noun ‘province’ i.e singular, is preceded by a plural noun, i.e. ‘countries’; thus in order to make the sentence grammatically consistent, we need to use both nouns in their plural form. C- The verb ‘depend’ is strictly followed by the preposition ‘on’. You can always depend ‘on’ something, rather than ‘in’ something. E.g: I can always depend ‘on’ you for my secrets OR I can always confide ‘in’ you. - Both the sentences ultimately mean the same but use different sets of words. Correct Sentence : While COVID-19 makes no difference between rich and poor, countries and provinces , a lot can depend on  the treatment where the person is when it comes to quality and cost of treatment.
